4 Claims.

The present invention refers to combination doors, and more particularly relates to a newtype of doors, constructed of wood, metal or other suitable material, and adapted to have incorporated therein a slidable, flexible shutter and shut-' ter-lifting or operating mechanism.

It is known to protect doors and windows by means of separate shutters or blinds constituting either a second shutter door or a revolving shutter as elements completely independent from the proper doors or windows to be protected.

The principal object of our invention consists of the provision of doors adapted to comprise a slidable shutter incorporated therein in such a manner as to form a single unit, which may be completely manufactured as such in the factory and may be readily applied to the respective door opening of a building without special installations and arrangements having to be made.

Another object of the invention is to provide in the door structure the necessary space and sufficient support for the slidable shutter and its operating mechanism. For this purpose, according to our invention, the frame of the proper door, especially, the side pieces of the lower door portion, as well as the intermediate and lower cross bars, are substantially stronger than the equivalent parts of an ordinary door, and the lower door portion is provided with double panels so as to form a hollow space or casing, which according to another feature of our invention serves to receive the slidable shutter in its lowered position so as to completely hide it therein in the mentioned condition.

In connection with this latter object, another feature of our invention resides in a new door structure which in appearance does not essentially differ from an ordinary door. As already stated, when the shutter is lowered it remains completely in the casing provided in the lower door portion. The shutter operating mechanism,

according to this invention, is also completely hidden due to its being fixed to the relatively strong intermediate cross bar in a corresponding cavity produced therein and due to its operating the shutter by means of an endless belt extending only into the hollow lower door portion.

A further object of our invention is to provide guide members on the inner surface of the side pieces of the door for conducting the slidable shutter from its lifted to its lowered position and vice-versa so as to secure an easy operation of said-shutter andto avoid any difficulty therein. These guide members may be constituted by U- shaped metal bars or by longitudinal grooves directly cut in the material of said side pieces and adapted to receive the ends of the diiferent rods of which the shutter is composed.

Another object of our invention is to provide a combination door permitting its upper portion to be composed of a plurality of small windows or easements or of a single casement, which will be emciently protected when the shutter is lifted. The shutter which preferably is to be used in connection with our new door structure is of the class comprising a plurality of conveniently interconnected rods having mortices or notches to permit the air to freely pass; therethrough. Thus, provided that the casement or easements are opened, circulation or ventilation of air is secured even if the shutter is in its lifted position.

Still another object of our invention consists in that even in this new combination door, we provide for the application of an insertible frame comprising a metallic screen, for preventing gnats and mosquitoes from entering the house equipped with our improved doors.

With such objects in view, and others which will appear as the specification proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended thereto.

In the accompanying drawings which, by way of example, illustrate the invention and wherein like reference numerals indicate corresponding parts in all the different views,

Figure 1 is a front elevation of a double wing door according to our invention, with the shutter in lifted position, this view being partly fragmentary so as to show theshutter lifting mechanism;

Figure 2 is a vertical sectional view showing the lifting mechanism and the shutter. inits lowered position;

Figure 3 is a cross section through the door,

parts outside of the plane of the paper being shown in elevation.

Referring to the accompanying drawings, the door as shown in Figure 1 is a double wing door,- but since each of the wings comprises an individual shutter and its accompanying lifting mechanism and may be considered as an independent element, in the following description, the term door refers to one of the wings or indifferently to,

a; one-wing door.

The door according to our invention is of a construction comprising an upper portioncomprised of a plurality of small windows or casements 1, or else constitutedby a single casecasing formed by the double-panels 2.

for a mechanism for operating said shutter '7."

The door frame does not comprise a lower cross bar, but the lower ends of the side pieces 6 which are covered by the end portion 5 of the panel 2 are connected to each other by means of a metal shaft 32, serving at the same time for other purposes which will be hereinafter described.

By the provision of said shaft 32, instead of a" lower cross bar, the casing formed in the lower door portion is left open, whereby the air can circulate freely therethrough and dry the shutter if it is lowered in wet condition, and whereby any water which entered the casing from above may be drawn off.

As has been clearly shown in Figure 2, the top cross bar 4 may be of normal size, but the intermediate and'bottom cross bars 3 and 5, respectively, are of greater thickness than those of an ordinary door, and as will be readily understood, the side pieces 6 between the two last-mentioned cross bars are broad enough to correspond to the latter and to permit the proper application of the "panels 2, which thus, together with the aforementioned'elements 3, 5 and'6, form a casing for the reception of a slidable shutter in its lowered position.

The slidable shutter 7 is of the class composed of apluralityof horizontal rods having mortices 11 for ventilation purposes and'being conveniently connected to each other by a flexible band-l2 which passes through corresponding perforations provided for this purpose in' all intermediate rods and arefixed tothe upper rod 13 and lower rod 14 by'means of suitable screws or rivets 15.

As has been clearly shown on the annexed drawings, the slidable shutter 7is disposed'at the outerface of the door, and when the same lowered it remains completely'hiddenwithin the In order to secure an easy operation of the shutter and to avoid any difliculty in lifting or lowering the latter, the side pieces 6 of the door are provided with'longitudinal guide grooves 18 in which the ends of the shutter rods may readilymove up and downwardly. These grooves may be out directly inthe material of the side pieces 6, if these are of sufficient thickness as it is always the case in the lower door portion, While in the upper door portion, according-to our invention, we provide special U-shaped metal bars attachedto saidside pieces 6 by any suitable fastening means-such as s'crews'l9 (Fig. 3). According to what'has been illustrated in Figure 2, thegroove 18 starting immediately below to upper cross bar 4 goes straight down tothe intermediate cross bar 3, proceeds through the body of the latterinto-the lower door portion along the outer panel 2, forms a loop near the bottom of said casing, and goes straight up again along the inner panel 2 untilit encounters the cross bar 3. These guide grooves 18 provided in both side pieces 6-'determine the whole way of the'shutter inits up and down movements and establish the-proper application of'the shutter tothe-door, as shown in connec- --tion with one wing'of the'double wing doorof Figure 1. As shown in Figure 2, the upper rod 13 of the slidable shutter comprises outwardly and inwardly overlapping portions or shoulders 16 and 17, respectively, which when the shutter is in its lowered position rest upon the intermediate cross bar 3 and thus prevent the entrance of water or the like into the casing of the lower door portion. 7 p

The intermediate cross bar 3, as already stated, is of sufficient size to provide therein a cavity for the reception and application of the shutter lifting mechanism. This mechanism maybe of "any convenient form adapted to cooperate with an endless belt as illustrated in Figure 2. The shutter lifting mechanism shown in said figure is composediof. a detachable handle'20 adapted to engage the shaft 21 of a bevel pinion 22 which cooperates with another similar pinion 23. On theshaft of the latter pinion a toothed wheel 24 is mounted which engages the toothed wheels 25 and-26; These toothed wheels impart their mo- 'tion to the rolls 27,28 and 29, respectively, by means of their individual common shafts on which both elements are mounted. Said wheels and rolls are shown arranged vertically one above the other, and the upper wheel 25 as well as its corresponding roll 28 are of greater diameter than the lower ones, in order to secure a smooth working of the lifting mechanism'and to diminish the energy required for lifting the shutter.

This lifting mechanism as hereinbefore described cooperates with an endless belt 30 fixed tothe last shutter rod l4-by rivets 15 or like fastening means. Said endless belt 30 is passed through the shutter lifting mechanism so as to be operated by thefriction exerted by the rolls 27-29-and 2728, and in order to'maintain a cer-' tain tension of the belt, the same is passed over an idler pulley 31 disposed near the bottom of the casing formed by the double panels 2-in the lowerdoor portion. Said pulley 31 is mounted onthe shaft 32 fixed at both ends by plates 32 andscrews33to the side pieces'6within the loop formed by'the groove 18. Inorder toprevent said belt 30 while'passing around the pulley 31 from being displaced laterally, the latter is provided with circular shoulders 34 thus serving as guide members for the belt 30. Further, in order to avoidan'eventual contact with'the toothed wheels 24, 25 and 26 while passing between the rolls I 27-29 and 27-28, these rolls are separa'tedfrom the said toothed wheels, and from the pinions 22 and 23 bymeans of lateral partitions 35and 35 arranged at right angles and fixed by screws 36 to the intermediate cross bar 3. v

When turning the handle 20 in order'to lift'the shutter, the endless belt 30 is operated by the friction rolls 27, 28 and 29, thus forcing the shutter along the grooves 18 into its lifted position shown in Figure 1. In order to retain the belt and simultaneously the shutter in said'lifted position, aloose pulley 37 is provided to cooperate with thelower friction roll 29in such a way that the belt 30, under the pressure caused .by the weight of the cutter, will contract into-wrinkles sufficient to impedev its passing between said two elements 29 and37 which are arrangedso. closely toeachiother that under suchcircumstances the belt cannot pass therethrough, but is'firmly re-' .tainedand thus prevents'the' shutter fromfalling backspontaneously.

It: will be: appreciated: that in 'the embodiment 'as showni and described, the friction rolls as;v well as 1 their associatedztoothed wheels are arranged;v

vertically, and that also other arrangements may be used, for instance, in triangle formation, if there is sufficient space available for doing so, this triangular arrangement often being preferable due to its being more effective in operation because of a better friction exerted by the rolls in this exemplification.

Referring once more to Figure 3, the same clearly illustrates a casement having glass divisions 8 and being adapted to be opened around the hinge 9 and to be firmly closed by the handle 10. It also shows the grooves or groove forming U-shaped metal bars 18 for the shutter, and it will be seen that a free space is left between the easement and the shutter in lifted position, which is sufficient to insert therein a rectangular removable frame (not shown) comprising a metallic screen destined to keep off gnats and mosquitoes when the casement is open, the shutter being either lifted or lowered.

It will be understood that the present invention is by no means restricted to the proper arrangement as herein before described and as shown in the annexed drawings, but that modifications may be introduced as to the disposition of different components of the device and in other respects without departing from the scope of the inventive principle and of the following claims.
